That’s resin printing that you need good ventilation for. I think there are some that are safer than others but for fdm which is the melting plastic and extruding it in lines there is no issue being indoors.
You can also make enclosures for them though so they are isolated

Old article but I’m sure the science hasn’t changed: hackaday.com/…/3d-printing-fumes-new-science/
Basically, if you are printing with PLA you are probably pretty safe. But I still don’t think I would sit in a tiny closet and hotbox with my printer. An open window or carbon filters on your HVAC are probably more than sufficient. And PLA is the most popular type of filament, so you aren’t limited much there. Unless you need higher temperature parts to withstand sun or car interiors. Then you are getting into materials you want to start looking into better ventilation for.

Even that, I’ve got a center console organizer in my car made of pla and it hasn’t deformed at all. So as long as it’s not in the direct sunlight

Yeah, I mostly print PLA, and occasional PETG. My printers are in enclosures as well and while I don’t have any dedicated ventellation system, they are by a window that has a fan blowing outside. I’m not too worried about it.
